Charlie Anderson, an analyst with Dougherty & Co., rated GoPro's stock a buy shortly before it went public, citing the value of its brand and its potential to become more of a media company.

GoPro generated nearly $1 billion in revenue for 2013, up from about $526 million the year before, and the company is profitable. However, GoPro is not without risks. The company noted in its S-1 filing that it faces potential competition on the hardware front and that it may not be able to pull off its media ambitions.
